Commentaries on this disc:

Bress and Gruber do a good job of covering many aspects of the film. They are entertaining but occasionally throw in some fairly odd, juvenile humour and comments.
Two points I want to make that are interesting about these two. Neither have directed again in over 10 years. Also they reveal that in the director's cut they thought that their original ending was the better one even though audiences thought ( spoiler ) that the main character killing themself as a form of absolute sacrifice and erasing their entire existence might be thought of as possibly negative and unnecessary. Well go figure. In this case the theatrical release is probably the better one. I understand their thinking about selfless sacrifice being the ultimate gift but it's not very life-affirming and ultimately leaves it with a negative spin. I, and most other people would rather see a win/win because...why not? I mean Jesus, they're premise is 'the world would be better off without me'? I think the world is much better with me in it, but hey, I guess that's just me not getting caught up in messed up self hatred. If you like the lead character you want them to gain something. Anything. Killing off your lead character as being the main problem in the movie is pretty dark. It's the exact opposite from what I wanted for this character.
